Rear 3 inch wheel studs

[Right on the Mark]

Starting the end year push with Red Dragon again. Needed to install these to run the Weld Prostars on the rear. Already redrilled hubs to 4.500 last year. The new studs knurl dia is .595 so drill size needs to be .580 which is 37/64. Could they pick any weirder of sizes for these things there all that way no standard drill sizes to install them.

I made new redrill fixture because old one would not allow 37/64 bit.I made drill guide whole length of drill to support 100%.

Fixture on. I needed the studs 100% correct spot because Welds are stud centric.

Studs go in no problem, just have to slip them into hub thru the area where the caliper was.

I cannot stress using good drills. My new chicago/lithtrobe USA drill cut thru like butter. USA USA.

What's nice is besides static weight I will be loosing alot of rotational weight which is a min 8 to 1 ratio.

Are the back of the holes in the rotor chamfered? Are you planning on the Weld ProStars being on full time?

I had to open up the holes in the rotors because the .595 knurl dia sticks up from the hub. Different rims go on her at different times. I will need some real cheapy winter tires thou to put on her.

You will have to use open lug nuts for the street wheels since the studs are about 1" longer than stock?

Yep I will have to drill my GT rim center caps so those poke out.

haha..before I saw this I was picturing the studs sticking wayy out with the GT wheels on there...drag car status. Now you'll just have to leave the rubber on the rear bumper and the shoe polish on the windows.

Just a FYI if anyone wants to run 8 inch wide welds with 5.5 inch backspacing and what needs to be done to clear stuff. I didn't want to run 1/4 or 3/8 thick spacer to clear caliper. I milled this part down to .190 thick.

Also this area needed to be takin down. I also had to use outer pads that only has 1/8 inch of pad material on it. This moves the caliper toward inside of car away from rim.

I run the same Weld wheels and only had to round the outer top radius of the caliper using the Cobra rotors and rear brake caliper relocation brackets. The caliper brackets cleared with no problem.









Not much of any way to take pictures of the caliper with the Weld wheels on.

Yep when you run cobra rotors out back that moves caliper up and into rim area that starts to flare out to outside of car. I switched back to all stock rear brake setup. I left caliper off and took .050 off bracket at a time till rim spun free then took another .050.

I was told to watch the clearance of the e-brake cables. They were close, so I simply double zip tied them tightly to the sway bar. You probably don't have that concern with the smaller rotor.

I had to clearance my front Calipers to clear my rims when I upgraded to "14.5 Rotors on my WRX. They clear my Sub Zero rims fine but had issues with my Rota Glides on the car. Hit a Pot Hole and they started hitting the rims


Really want to put a set of BIG ROTORS on my Mark to fill all the area Cobra R's have :shifty:
